Deep Mixing Method - Portland Cement Association

The deep mixing method (DMM), also known as deep soil mixing or cement deep soil mixing (DSM/CDSM), is an in-situ soil treatment in which native soils or fills are blended with cementitious and/or other materials, typically referred to as binders. Ground treated by deep mixing methods has higher strength and lower compressibility than untreated ...
